The Truman Café in suburban Albert Park doesn’t have super-trendy avocado toast on its menu, but it does serve an avocado side (4 Australian dollars) and some of the breakfasts are paired with the pear-shaped fruit, including the Truman Brekkie, which consists of sourdough toast, scrambled eggs, hash, avocado, beetroot relish and roasted seeds (17.50 Australian dollars).

The “Avolatte,” as the breakthrough beverage is called, has drawn some ribbing from those who find Millennial obsessions to be tiresomely trendy.

For instance, Texan Hunter Sosby tweeted that he would “die before I consume an avolatte.”

A Truman Café barista, Jaydin Nathan, was lighthearted about the drink, which started life after a request from a customer to have his latte served in an avocado skin. “It’s literally coffee in a piece of rubbish,” he said, though he defended the drink for its creativity.

"Maybe some people thought it was meant to be a joke,” he told the Australian Associated Press, “but food is meant to be fun, food is meant to be art."

The invention is just the latest attention-grabbing beverage cooked up by companies trying to attract the coveted Millennial consumer. It comes after Starbucks dreamed up the Unicorn Frappuccino – a limited-time concoction zeroing in on hipsters’ apparent obsession with unicorns – that changed color and taste as you drank it (and confusingly contained not a drop of coffee).
